Frame double wall electro socket

Protective frame-cover under 1,5 electro socket (double sockets to one wall post).
Haven't found any so made my own.

1 mm thickness on edge to 2 mm to central hole,
3 mm height.

Print 0,1-0,2 mm to avoid "stair" effect
or 0.4 vertical on long side with brim 10-20mm –
check images above.
